Objective To observe the function and survival of parathyroid cells cultured under simulated microgravity condition after cotransplanation of syngeneic allogeneic testicular sertoli cells.Methods Parathyroid cells in SD rats were assigned to flask-culture or bioreactor-culture.Allogeneic testicular sertoli cells in SD rats were cultured by using routine method.The recipients of hypoparathyroidism Wistar rat models were divided into 3 groups randomly:group A,receiving parathyroid cells(cultured with routine method)transplantation only;group B,receiving parathyroid cells and allogeneic testicular sertoli cells(cultured with routine method)transplantation;group C,receiving parathyroid cells(cultured under simulated microgravity condition)and allogeneic testicular sertoli cells transplantation.Allograft survival,change in cell components,apoptosis of infiltrative lymphocytes and parathyroid cells function were analyzed after transplantation respectively.Results The average survival time in group A,B and C was(17.3±1.6),(43.2±2.4)and (52.5±1.5)days,respectively.There was significant difference among group (P<0.05).In group C,parathyroid cells with strong secreting function grew into scaffold materials and adhered to them.FasL-expressing testicular cells and apoptotic lymphocytes were quite evident between allograft and kidney parenchyma.Conclusion Parathyroid cell cultured under simulated microgravity condition enhances its survival and function after cotransplanation of allogeneic testicular sertoli cell with immune privilege.

Objective To explore the effects of nursing human resources training and performance appraisal information management in a grassroots hospital. Methods From January 2017, Beilun branch hospital, the First Affiliated Hospital of Zhejiang University, carried out self-developed nursing human resources training and performance appraisal information management. We selected 50 nurses before information management (between July to December 2016) and 50 nurses after information management (between January to June 2017) as subjects. And then, we compared the theoretical examination achievements, operation examination achievements, the score of nursing quality and satisfaction with training of nurses before and after implementation. Results After information management the scores of theoretical examination achievements, operation examination achievements, the score of nursing quality of nurses were (93.48±1.95), (94.98±1.87) and (95.43±1.05) respectively higher than those before information management with significant differences (t=17.088, 18.035, 20.392;P<0.01). The satisfaction rate of nurses increased from 64.00% to 96.00% with a significant difference (χ2=16.000,P<0.01). Conclusions The application of information management in nursing human resources training and performance appraisal in a grassroots hospital can improve theoretical and operation examination achievements, increase satisfaction with training of nurses and improve nursing quality. It is worth to be popularized and applied in grassroots hospitals.

Objective To assess the change of sexual behaviors before and after HIV was recently identified among men who have sex with men(MSM). Methods A retrospective study was conducted on recently identified HIV-infected MSM in Chengdu and Tianjin. A face-to-face questionnaire interview was administrated to collect sexual behaviors within six months,before and after HIV was diagnosed. Differences in sexual behavior before and after the diagnosis were assessed, using the McNemar χ 2 test. Logistic regression analysis was conducted to identify predictors for sexually risk behaviors. Results Of 129 HIV-infected MSM under survey,the average age was 31.8 years and the main venue in seeking male sex partners was through Internet. The proportions of MSM with unprotected anal intercourse (UAI) decreased from 70.5% before diagnosis to 16.3% after diagnosis and the percentage of having more than 1 partner decreased from 66.7%before diagnosis to 33.3%after diagnosis. After the diagnosis was made,there appeared a significant decrease in the percentage of persons who had one main partner from 72.9% to 55.0% and having casual partners declined from 62.8% to 31.0%. Data from multiple logistic regression analysis revealed that risk factors as UAI before diagnosis,more than 1 partner after diagnosis and having one main partner,were all significantly associated with UAI after diagnosis. After the diagnosis was made for UAI,risk factors for‘having more than 1 partner’after diagnosis,would include:using Internet to seek for sexual partners,after diagnosis,having one main partner but not disclosing to him. Conclusion After the diagnosis was made,most HIV-infected MSM would reduce their high risk sexual behaviors but some continued to practice UAI.

After the diagnosis was made for UAI, risk factors for 'having more than 1 partner' after diagnosis, would include:using Internet to seek for sexual partners, after diagnosis, having one main partner but not disclosing to him.

CONCLUSIONAfter the diagnosis was made, most HIV-infected MSM would reduce their high risk sexual behaviors but some continued to practice UAI.
